Mobile Device Accessory for Universal Test Strip Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with chronic diseases need to carry multiple in-vitro diagnosis (IVD) devices due to the requirement of different test strips for various measurements, which is inconvenient and inefficient.
Innovation Solution
A mobile device accessory that includes a mobile device adaptor and a test strip adaptor, allowing different types of test strips to be used with a single mobile device by aligning the test strip's reaction area with the device's camera and light source for image capture and analysis, eliminating the need for multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If patients use multiple standalone IVD devices for different test strip types, then measurement capability is improved, but device portability and convenience deteriorate
Solution Approach 1:
The mobile device accessory enables a single device to perform multiple IVD measurement functions by supporting different test strip types through interchangeable adaptors, making the device universal for various measurements while maintaining portability
Solution Approach 2:
The accessory employs a nested structure where the test strip adaptor fits within the mobile device accessory housing, and the reaction area positioning mechanism is integrated within the adaptor, creating a compact nested arrangement that maintains portability
2Adaptability or versatility
If patients carry multiple standalone IVD devices for different test strip types, then measurement versatility is improved, but the quantity of devices increases
Solution Approach 1:
The mobile device accessory serves as a universal platform that can accommodate different test strip types through interchangeable adaptors, allowing one device to replace multiple specialized devices while maintaining measurement versatility
Solution Approach 2:
The invention merges the functionality of multiple standalone IVD devices into a single mobile device accessory by integrating the light source, camera, and adaptable test strip interface into one unified system
3Measurement precision
If existing IVD systems use specific light sources and optical sensors, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The invention replaces traditional standalone IVD device optical systems with a mobile device-based optical system, using the mobile device's camera and light source instead of dedicated medical-grade optical components, thereby reducing device complexity while maintaining measurement capability
Solution Approach 2:
The accessory design uses universal components (mobile device camera and light source) that can serve multiple measurement functions across different test strip types, reducing the need for specialized complex optical systems for each measurement type
